DOORLOCK.

Patented Feb. 28, 1911. Serial No. 554,703.

To all whom it may concern:

Be it known that I. HARRY M. Minn. a citizen of the United States,residing at Kenosha, county of Kenosha, and State of Visconsin, haveinvented certain new and useful In'iprovements in Automobile Door-Locks, of which the following is a specification.

My invention relates to improvements in automobile door locks and hasfor its object the production of a device of this characten which shallbe inexpensive of manufacture and ctlicient in its operation.

A further object of my invention is to provide an automobile door lockwhich may be readily foot-operated by a person sitting in theautomobile.

Other objects will appear hereinafter.

Vith these objects in view my invention consists in the novelconstruction and arrangement of parts which will be hereinafter fullydescribed and more particularly pointed out in the appended claims.

My invention will be more readily under stood by reference to theaccompanying drawings forming a part of this specification, and inWhich,

Figure 1 is a side elevation of an automo bile embodying my invention inits preferred form, Fig. 2 is a detail perspective showing a foot leveremployed in the device, Fig. 3 is a detail perspective view showing ahandle used to operate the lock, Fig. 1 is a fragmcntary view showing aportion of the automobile door in section and the operative parts of thedoor lock, and Fig. 5 is a detail side elevation.

Referring now to the drawings, 1 designates an automobile which may beof the inclosed type as shown or of any other type in which a door isprovided.

2 designates a side door and 3 the door casing, a lock casing 4 beingprovided and secured in said door, as clearly shown in Fig. 1.

An arbor 5 having a handle 6 integral therewith is fitted to the lockand extends inwardly therefrom to receive the foot lever 7, the latterbeing provided with a pedal. 8 at one end and a square opening 9 at theother to receive said arbor. The foot lever 7 is detachably secured tothe arbor 5 by means of the set screw 10, the construction thereof beingshown in detail in Fig. 2.

Pivoted in the lock casing 1 and projecting outwardly therefrom 1s alatch lever 11 l the same being located near the center of said lockcasing. A latch catch 12 is secured to the door casing 3 and formedthere in is a catch proper 12. the latch lever having an inclinedsurface to engage said catch and to facilitate the raising thereof. Thelatch lever 1.1 is adapted to pass over the catch 12 and to drop intothe recess 13 when the door is locked. The latch lever 12 is held in itslowermost or normal position by means of a leaf spring 14f which islocked in the top part of the lock casing at and is adapted to rock overthe projection 15 formed in said lock casing. In order to raise thecatch lever 11 an oscillatory cam 16 is provided. the same having asquare openi ng to receive the arbor 5 by means of which A it isoscillated. A stop 17 is provided in the cam 16 which engages aprojection 18 formed in the casing 4- for limiting the movement of saidcam. Three different means are provided for operating the latch lever 11and one of which comprises a bellcrank lever 19 which is fulcrumed inthe top of the door, as illustrated in Fig. 4, said lever having ahandle 20 by means of which the same is operated. A connecting rod 21connects the bell-crank lever 19 with the latch lever 11, so that whenthe handle 20 is moved rearwardly by the operator said latch will raiseout of the recess 18 when the door may be pushed open. The latch lever11 may also be raised by turning the handle 6 in the usual manner, orthe foot pedal 7 may be used which is depressed by the operator asindicated by dotted lines in Fig. 1. It will be noted that any one ofthe means provided for operating the lock will operate efliciently andthat any one of these means may be used as best suits the convenience ofthe operator.

While I have shown what I deem to be the preferable form of my improvedautomobile lock, I do not wish to be limited thereto as there might bevarious changes made in the details of construction and arrangement ofparts described without departing from the spirit of my invention, andhence I desire to avail myself of such changes and alterations as fairlyfall within the scope of the appended claims.

Having described my invention what I claim as new and. desire to secureby Letters Patent is:

1. In an automobile door lock, in combination with a door and doorcasing therefor, of

a latch catch secured to said casing a latch in said latch casing andprojecting therefrom for cooperation with said latch catch anoscillatory cam mounted in said casing for raising said latch, means forlimiting the oscillation of said cam, an arbor secured in said cam, anda foot lever detachably secured to the inner end of said arbor and ahandle secured to the outer end thereof, substantially as described.

2. In an automobile door lock, in combination with a door and doorcasing therefor, a latch catch on said door casing, a latch cas ingsecured to said door, a latch pivoted in said latch casing andprojecting therefrom for engaging said catch, a spring over said latchadapted to depress the same, a cam under said latch for raising thesame, a detachable foot lever arranged on the inside of the door andconnected with said cam and a hand lever projecting from the top of thedoor connected with and adapted to raise said latch, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
